Definitions

  • the present invention pertains to a respiratory patient interface used to deliver gas to a user.
  • the present invention is related to a respiratory patient interface having a cushion with a flap having a frustum-shaped portion.
  • Obstructive sleep apnea or OSA, obstructive sleep hypopnea, and upper airway resistance syndrome are among a variety of known disorders characterized by episodes of complete or partial upper airway obstruction during a state of diminished consciousness, such as sleep, anesthetization, or post anesthesia.
  • OSA, hypopnea, and UARS cause intermittent interruption of ventilation during sleep with the consequence of potentially severe oxyhemoglobin desaturation.
  • those afflicted with OSA, hypopnea, and UARS experience repeated, frequent arousal from sleep in response to the oxygen deprivation. The arousals result in sleep fragmentation and poor sleep continuity.
  • Consequences of OSA, hypopnea, and UARS may include debilitating daytime sleepiness and cognitive dysfunction, systemic hypertension, cardiac dysrythmias, pulmonary arterial hypertension and congestive heart failure. Other consequences may include a predisposition to myocardial infarction, angina pectoris, stroke, right ventricular dysfunction with cor pulmonale, carbon dioxide retention during wakefulness as well as during sleep, and continuous, reduced arterial oxygen tension. Moreover, the cognitive impairment resulting from OSA, hypopnea, and UARS puts those afflicted at elevated risk of accidents.
  • OSA, hypopnea, and UARS can include both anatomic and functional abnormalities of the upper airway that result in increased airflow resistance. Such abnormalities may include narrowing of the upper airway due to suction forces created during inspiration, the effect of gravity pulling the tongue back to oppose the pharyngeal wall, and insufficient muscle tone in the upper airway dilator muscles, among others. It is also believed that excessive soft tissue in the anterior and lateral neck, as commonly observed in obese persons, can apply sufficient pressure to internal structures to narrow the upper airway and restrict airflow.
  • a typical positive airway pressure device comprises a gas source (e.g., a blower, gas storage container) that delivers gas via a delivery conduit to a patient interface, such as a mask.
  • a gas source e.g., a blower, gas storage container
  • CPAP continuous positive airway pressure
  • variable airway pressure such as a bi-level pressure that varies with the patient's respiratory cycle, or an auto-titrating pressure that varies with the monitored condition of the patient.
  • Pressure support therapies are also provided to treat other medical and respiratory disorders, such as Cheynes-Stokes respiration, congestive heart failure, and stroke.
  • This mask has an outer shell coupled to a cushion which includes a coupling portion, a middle portion, and a flap portion.
  • the coupling portion couples the cushion to the outer shell; the middle portion provides clearance between the flaps and the coupling portion; and the flap portion has flaps that are inwardly directed such that they face one another.
  • this mask includes a variety of features to vary the amount of support and/or sealing provided by the cushion to balance the competing goals of comfort and functionality locally. In some locations, more support may be required. In other areas more flexibility may be required. This application discloses several alternatives to achieve this goal.
  • the cushion may include one or more pleats, the wall thickness may be varied to adjust the amount of support, or flexibility may be adjusted portionally about the cushion.
  • this device still utilizes inwardly directed flaps which may not form an optimum seal on some users. Instead, the flaps may tend to crumple or buckle.
